Patented Sept 16, 1952 UNITED sTAri-zs rArsNr- ELECTRIC LAMP HAVING AnEvoLvAnLnv SHADE STRUCTURE I I Joseph Palmi eri, fiuiialo N. Y. Application May20, 1949, Serial N 0.9%476 A Claims. (01. tripled) This invention relates to improvements in ornamental lighting devices and'more particularly to an electric lamp having a revolvable shade structure.

The primaryobject of the invention is to provide an electric lamp having a revolvableinner shade which is viewable through a stationary outer shade whereby a highly attractive and ornamental effect is produced, such inner shade bearing indicia or designs of appropriate type to render the lamp suitable for use either in the home or in stores for purposes of attracting attention or advertising.

Another object is to provide such a lamp which is simple in construction, not likely to get out of order, but if so it can be readily repaired including the replacement of parts, and is relatively inexpensive to manufacture.

Other objects and advantages of the invention will be apparent from the following description and accompanying drawings wherein:

Fig. 1 is an elevational side view of an electric lamp embodying the invention.

Fig. 2 is a view similar to Fig. l but showing the outer shade in vertical central section so as to expose the inner shade and associated parts.

Fig. 3 is a fragmentary vertical central sectional view, on a slightly enlarged scale, through I the revolvable inner shade structure shown in Fig. 2.

Fig. 4 is a view taken .along line i-4, Fig. 2 and showing the revolvable inner shade in elevation and viewed from the top thereof.

Fig. 5 is an enlarged fragmentary section of the means shown in Fig. 3 for mounting the revolvable inner shade for rotation.

The lamp illustrated in the drawings is of the table type and includes a base 10 having an upright pedestal post ll rising therefrom and an electric bulb l2 arranged in a socket 13 of conventional form mounted in any suitable manner on the upper end of the pedestal ll.

To produce a highly attractive andornamental eiiect using the light emitted from the electric bulb l2, a revolvable inner shade It surrounds the electric bulb l2 and in turn is surrounded by a stationary outer shade I5. The revolvable inner shade It bears indiciaor ornamental designs of any desired type, that indicated at It in Figs. 1 and 2 being for purposes of illustration only. The skirt portion of the inner shade H3 is shown as being of downwardly flaring frustoconical form and is made 'of transparent or translucent material so that the indicia 15 will stand out by contrast and be viewable from the exterior of the inner shade. For example, the skirt portion of the inner shade It can be composed of a translucent parchment on which the indicia I6 can be painted or otherwise applied in contrasting colors.

The skirt portion of the stationary outer shade I5 is shown as being bell-shaped and is also made of transparent or translucent material so that the design or indicia It on the revolvable inner shade M can be viewed through the stationary outer shade l5. the outer shade I5 can be made of any of the usual finely .woven textile materials used in conventional types of lamp shades. Further, the skirtportion of the outer shade l5 can be of any color or combination of colors or carry any suitable design for co-operation with the design or indicia IS on the revolvable inner shade It. However, no design is shown on the skirt portion of the outer shade l5.

Means are provided for supporting the inner and outer shades l4 and I5 respectively on the pedestal post II in such manner that such means are covered by the skirt portion of the outer shade. For this purpose a horizontal arm 18 extends laterally from one side onlyoi the pedestal post II at the upperend thereof and can be mounted on this pedestal post in any suitable manner.- The horizontal arm I8 is arranged adjacent the lower edge of the outer shade l5 and it is desirable not to have this arm arranged below this edge so that it will not be exposed from the usual angles of view.

A rod I9 is shown as extending vertically upwardly from this horizontal arm I8 adjacent the inner end thereof, the upper end of. this rod being bent at right angles as indicated at 252 to extend radially toward the longitudinal axis of the pedestal post ll. While any suitable means forconnecting the lower end of the rod IS on the horizontal arm l8 can be employed, the means shown comprise nuts 2! and 22 arranged above and below respectively the horizontal arm and on the threaded lower end of the rod which extends through a hole provided in this arm, the nut being tightenable against the upper side of this arm and the nut 22 against the lower side thereof. The rod l9 is thus rigidly held on the rod in any suitable manner such as by Welding. The bracket 23 is in the form of a rigid The skirt portion of ber 28 arranged on the upper side of the bracket 23. By turning the screw and nut members 25 and 26 respectively, the same can be firmly clamped to the bracket 23. The nut member 28 is provided with a vertically extending recess 28 opening to the upper end of this nut member. The spindle or needle 24 is removably arranged in this recess 28 and is held fast to the nut member 26 by a thumb screw .or set screw 29 arranged in a threaded hole which extends through the wall of the nut member. The inner end of this thumb screw 29 is adapted to engage the lower end 'of the spindle or needle 24 as shown in Fig. 5. The longitudinal axis of the spindle or needle '24 is substantially coaxial with that of the pedestal post II.

The inner shade I4 is mounted on the upper pointed end of this spindle or needle 24 for rotation. For this purpose theupper end of the skirt portion of the inner shade I4 is shown as being covered by an end head 30. Referring toFig. 3, this end head 30 is shown as being provided with a dependin continuous annular flange '3I surrounding a cylindrical annular flange 32 formed on the upper end of the skirt portion of the inner shade I4. These flanges 3I .and32 are connected by a series of rivets '33. The end head 39 is'shown as being provided with a central opening through which the threaded shank of a screw member 34 extends, the lower end of this screw member "being enlarged to provide a head35'which bears against a lock washer 36 interposed between this head 35 and the lower side of the end head 30. A nut member 38 is arranged above the end head 39 to work on the threaded shank of the screw member 34 and this nut member 38 .can be tightened so as to clamp theend head 30 firmly between these members. The screw member 34 is shown as being provided with a central vertical axial passage 39 extending completely therethrough. Adjacent the lower end of the head 35 the axial passage 39 is formed to provide an upwardly facing annular shoulder on which a cylindrical bearing block 40 rests. This bearing block 40 is held against this shoulder by an externally threaded retainin screw 4I arranged in the upper portion of the axial passage 39 which is internally threaded to receive this retaining screw. The lower end of the retaining screw engages the upper side of the bearing block 40 and the upper end of this screw does not extend above the upper end of the screw member 34, as shown in Fig. 5.

The lower face of the cylindrical bearing block 49 is preferably slightly centrally recessed as indicated at 42 to receive the pointed end on the spindle or needle 24 which projects upwardly into the lower end of the axial passage 39. The bearing block 48 is composed of any suitable material which minimizes friction between the pointed end of the spindle or needle 24 and this block is preferably made of quartz.

The inner shade I4 is revolved by the passage of heated air through the end head 33. For this purpose this end head 39 is provided with a series of generally radiating downwardly turned vanes or louvers 43 preferably struck out from this end head thereby leaving openings 44 associated with these vanes or louvers 43. The passage of heated air upwardly from the interior of the inner shade I4 through these openings 44 and past the vanes or louvers 43 will cause the shade I4 to revolve on the pointed end of the stationary spindle or needle 24.

Should the point on the spindle or needle become worn, the same can be readily replaced by FIOOSBIlllIlg the thumb screw 29 thereby permitting the spindle or needle to be withdrawn from the recess 28 and be replaced by another needle or spindle which can be made fast to the nut member .26 by again tightening the thumb screw 29. Likewise, if the bearing block 40 becomes Worn, the same can be withdrawn from the screw member 34 :by first removing the nut member 38 and then unscrewing the retaining screw 4I holding this hearing .block in position. With the bearing block 40 .so removed from the screw member 34. the'dished operative face 42 can be redressed and the block reinserted in the screw member or the defective block can be replacedby a similar bearing block,

The outer shade .I5 is mounted in a stationary position .and for this purpose an outer rod 45 is shown .as being mounted .on-the horizontal arm I8 adjacent the outer end thereof in a manner similar to that used for mounting the inner rod I9. Thus, the nuts 45 and 48 arranged respectively above and below the horizontal arm I8 and working on the lower threaded end of the outer rod 45 can be tightened against this arm to connect this outer rod rigidly to the horizontal arm Ill. The outer rod 45 is preferably shaped to extend generally along the side of the skirt portion of the revolvable inner shade I4 and the upper end of this outer rod is shown as bein bent to extend horizontally and over the end head 39 on the inner shade and in spaced relation thereto. The upper end of the outer rod 45 is shown as being turned vertically upwardly so that the longitudinal axis of the upper end portion 49 is substantially coaxial with the longitudinal axis of the pedestal post II. This upper end portion 49 of the outer rod 45 is externally threaded and an outwardly extending flange 50 is shown as being fast to the outer rod 45 at the lower end of the threaded upper end portion 49.

The out-er shade I-5 can be of any suitable construction and is shown at its upper end as having a frame member 5i extending transversely across the upper end of the outer shade I5. This frame member 5i may be of the conventional spider-like frame construction conventionally employed in lamp shades whereby the frame member 5I is adapted to receive-the upper threaded end portion 49 of the outer rod 45 and rest on the flange 50 and be clamped thereagainst by a nut 52, in the usual manner.

Referring to Fig. .2,.it will be seen that support elements including .the horizontal arm I8 and innerand outer rods I 9 and 45 respectively are completely covered by the skirt portion of the stationary outer shade I5. Further, a lamp constructed as described above can be placed on a table or the like so that these rods I9 and 45 are on the far side of the lamp as usually viewed whereby these rods are generally unnoticed and the revolvable inner shade I4 appears to float during its rotation on the inside of the outer shade I5.

The inner and outer shades I4 and I5 respectively can be readily removed and replaced. Further, the spindle or needle 24 can be readily repaired or replaced as can also the bearing block ill, thereby insuring the continued operativeness of the lamp for indefinite periods of time.

As previously described, the skirt portions of the inner and outer shades can be decorated with any desired indicia or designs for advertising or purely ornamental purposes.
